Bertsch Panta 4 Corner Leisure Building: The Bertsch Panta 4 Summerhouse is both elegant and versatile featuring half glazed doors and smaller windows providing a slightly higher degree of privacy than our other buildings in this range, and giving the option of placing desks or tables underneath the windows. As with all Bertsch buildings, you are able to customise the building to suit your own purposes and design with other styles of doors and windows being available, and as this 45mm building also features double glazing, its perfect for year round use.
